How to read SKF 7338 BCBM
- 73Series
- Angular contact ball bearings, 73 series. For the same bore, each series has a different outside diameter and width.
- 38Bore
- 190 mm bore: 38 × 5.
- BCBMSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
7338 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF angular contact bearings of the BCBM series are components designed to support combined radial and axial loads. Their inclined raceway design allows angular contact between balls and raceways, making them suitable for applications requiring high precision and rigidity. They are used in industrial machinery, transmission equipment and systems where axial loads are present in one or both directions.
The designation of these bearings follows a clear scheme: the base number indicates the size and dimensional series. For example, 7224 BCBM corresponds to a bearing of the 72 series, with a bore diameter of 120 mm (code 24). The suffix BCBM identifies specific internal features, such as the contact angle and cage design. In the examples 7226 BCBM, 7228 BCBM and 7230 BCBM, the number increases progressively, reflecting larger dimensions. Knowing this nomenclature allows you to select the correct bearing for your application.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, food, petrochemical and machinery manufacturing. They are common in machine tool spindles, centrifugal pumps, compressors, gearboxes and power transmission equipment. Their ability to support combined loads makes them ideal for applications where simultaneous axial and radial forces exist, such as in helical gears or spindle systems.
To correctly select an angular contact bearing, take into account the magnitude and direction of the loads, the operating speed and the environmental conditions. It is essential to verify the sealing: these bearings can be open or sealed, which influences lubrication and protection against contaminants. Mounting requires precise alignment and, in many cases, controlled axial adjustment. Proper lubrication, whether grease or oil, extends service life. Follow the manufacturer's recommendations for internal clearance and tightening torque.
When looking for replacements, it is common to find equivalences between brands. Although part numbers may vary, the main dimensions and load capacity are usually standardized. For example, an SKF 7224 BCBM bearing may have equivalents in other brands with similar designations, but always verify the technical specifications. At MR Accesorios Industriales we sell genuine SKF bearings and can advise you on interchangeability.

Frequently Asked Questions
- What are the dimensions of the SKF 7338 BCBM bearing?
- The SKF 7338 BCBM bearing has a 190 mm bore, a 400 mm outside diameter and a 78 mm width (190 x 400 x 78 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 7338.
- What does the BCBM suffix mean on an SKF bearing?
- The BCBM suffix indicates specific internal features of the bearing, such as the contact angle and cage type. It is important to check the product page for exact details, as it may vary by size.
- Do these bearings support axial loads in both directions?
- Single row angular contact bearings support axial loads in one direction only. For loads in both directions they must be mounted in pairs, generally in back-to-back or face-to-face arrangement.
- How can I tell if a bearing from another brand is equivalent?
- You must compare the main dimensions (inner diameter, outer diameter and width) and load capacity. Part numbers may vary between manufacturers, so it is advisable to consult a specialist. At MR we advise you.
